Pittwater Road at Raglan Street Flood Mitigation Project
Manly Oval Stormwater Detention & Management System
The Manly Oval Stormwater Detention Project involves an in ground stormwater detention system. The purpose of the system is to reduce the risk of inundation and vehicle and pedestrian hazard at the Raglan Street and Pittwater Road intersection of Manly CBD.
The project involves diverting water from the existing underground stormwater pipe network into the detention system. The detention system will have the capacity of approximately one mega litre of in ground storage and other flood mitigation devices including:
- The management of peak flows during storm events to minimise inundation
- An upgraded to pits and pipes in Raglan Street
- Increase network capacity to further reduce inundation
- A detention system to manage stormwater from the 10 hectare catchment during a storm event
- An in ground sedimentation system to manage gross pollutant from the catchment
The project will provide the following benefits to the Manly Community:
- Reduce the frequency of storm related inundation in the vicinity of Raglan Street and Pittwater Road
- Improved stormwater quality flowing into Manly Beach during normal and storm events
- Improved management of local stormwater in and around the northern portion of the Manly Oval and along Raglan Street, Manly
Under Part 5 of the Environmental Planning and Assessment Act, 1979, Council carried out the Assessment and determination of the proposed works in the Review of Environmental Factors. A Determination with conditions was issued on 4th August 2014. The environmental assessment of the proposed works has indicated that there will be no significant impact on the surrounding environment. The works will not involve any threatened flora or fauna species and will specifically avoid the need to remove any significant trees.
Low Interest Loan Subsidy
The Local Infrastructure Renewal Scheme (LIRS) provides councils with a subsidy in interest costs to make it affordable to take out major bank loans to fund their projects. Manly Council applied for, and was successful in securing a Loan Infrastructure Renewal Scheme (LIRS) round 2, in mid August 2013 for this project.
The construction is due to commence in early February 2016 with a project timeline of 4 months. However, the field of play for rugby will be restored and returfed in time for the first home game that is scheduled for 16 April 2016.
